T0 at whom, it may concern.-

Be it known that we, GEORGE PETER AH- LERS and GEORGE ALEXANDER SCHAAL,Of the. city of Baltimore, State of Maryland, have indotted line AA. Figs. 3 and 4 are top viewsof certain parts of the invention.

Referring now to the drawings, 1 is the bottle-head, and 2 its neck.

3 is the bottle-mouth, and 4 its throat.

The ordinary cork whereby the bottle is closed is not shown in the drawings.

Within the throat 4 is afrusto-conical valveseat 5, the larger diameter of which is slightly less than that of the mouth 3. Seated in this valve-seat is the frusto-conical valve 6, which is inserted through the mouth 3. The upper edge of the valve 6 is preferably cutaway at, say, four points to form channels 7 for the passage of the contents of the bottle from around the valve toward its center as they are poured out, the valve being unseated as the bottle is partially or wholly inverted.

9 is a loose plate laid on the valve 6 to prevent access to the latter from the bottlemouth in an efiort to unseat the valve and so admit of refilling the bottle. This plate is preferably perforated to facilitate the discharge of the contents of the bottle. The removal of the valve'and plate is prevented by an open round-wire spring-ring 10, which rests Within an annular groove 11 in the bottle-mouth, and its distance above the plate 9 is such that it and the valve 6 may have the proper lift.

The bottle is filled before the valve and its attachments are in place, after which the spring-ring is forced into its groove, the ring vented.

\Ve claim as our invention- A bottle having in its throat a frusto-conical valve-seat, and above the valve-seat an annular groove, combined with a valve which is smaller in diameter than the bottle-mouth and thereby adapted to enter the bottle through its mouth to close the opening within the valve-seat, a loose perforated plate which rests on the valve and is susceptible to an upward movement in common with the said valve, and an open spring-wire ring having an inner diameter which is less than that of the perforated plate, which ring is seated in the said annular groove and serves to limit the upward movement of the said valve and its loose perforated plate, substantially as, and for the purpose specified.
